Robot forces Harry's submission before Sarah's capture"The robot’s reprogrammed directive to harm humanity (End of Episode 3) parallels its later internal conflict when Sarah pleads for reason (Beginning of Episode 4), highlighting the same tension between programmed obedience and emergent moral conflict."
